Hey.
I’ve got a login form with post as method. The action goes to ‘auth/login’ and will check the database if the user exists. If the user exists, I call the $this->getUser->setAuthenticated(true);. After this I want to redirect to a welcome page if success.

If the login failed, I would want to tell the user so in the view of course. But settings variables in the controller only if login failed, and check in the view if each of those variables are set, is a lot of work?

This means I have to check almost all variables I want to use in the view set from the controller. If it should happen that it is not set, and I just go ahead and echo it, I get an error from symfony, and production stage-mode-ish don’t show anything but an 500 internal server error .

Thanks

EDIT:

This is my current, new and better solution. Still looking for feeback.

in /templates/loginSuccess

if ($sf_params->has('bad_login')) {
echo "Wrong username or password";
}

And in my controller:

$this->redirect('auth/login?bad_login=');

    Take a look at how sfDoctrineGuardPlugin (the de-facto standard for authentication) does it: they created sfGuardValidatorUser and use it as a post validator in the signin form.

    Advantage of this method: the form takes care of the username/password validation, you do not need to put that code in your action. It simplifies that to a simple $form->isValid() { $this->redirect("@homepage"); }.
